Datasheet DTA123EE, DTA123EKA, DTA123EM, DTA123EUA Datasheet (ROHM) [ru]

-100mA / -50V Digital transistors
(with built-in resistors)

DTA123EM / DTA123EE / DTA123EUA / DTA123EKA

zApplications
Inverter, Interface, Driver

zFeatures

1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors.
(see equivalent circuit)

2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input.
They also have the advantage of almost completely eliminating parasitic effects.

3) Only the on/off conditions need to be set for operation, making the device design easy.
